Thanks for the hint about playing by folder, it will be good enough for me until a fix is available.
Something I don’t understand is that you say that it is not standard for you to have track numbers in your file names whereas you show examples of file names that actually have track numbers. Even if there have artists and albums in front of the number, your files are still sorted by track number inside an album.
As for me, a typical file name in my music collection will be
artist--year-of-album--title-of-album--track-number--track-title.flac, so not too far in spirit from yours, and the folder view will do the trick (at least for some time).
It’s still a bit awkward to have to scroll done quite a bit in a long list of files, but once I have spotted the file of the first track of the album I want to listen to, the subsquent tracks will follow as intended and the behavior of the previous and next buttons are OK too.
Not ideal, but already usable for me.
